Shaq dishes dime to Christina Aguilera for Oreo dunk

Shaquille O'Neal threw down plenty of flashy dunks over his Hall of Fame career, and now he's helping someone do the same thing - sort of.

In a new ad for Oreo, the retired NBA legend set up singer Christina Aguilera for a no-look, over-the-shoulder dunk ... of a cookie into a glass of milk.

Dunkalicious.
